Product Listing

UHV Series

Heavy duty tunnel access, push-pull linear motion feedthroughs allow linear displacement of heavy samples and components. The push-pull shaft is hollow providing tunnel access for instrumentation leads such as those used for thermocouple temperature measurements and other low voltage electrical applications. The vacuum nose piece is shipped with a blank ON 16CF flange which can be removed or modified to accept electrical feedthroughs as required. These devices do not provide position indication. Sample or component position must be verified visually through a viewport. Sample linear position can be fixed with an integral position lock knob mounted on the actuator housing. Unlike conventional motion feedthroughs, heavy duty models employ re-entrant welded bellows construction allowing the use of sturdier and larger diameter shafts.
